I was writing several stories about my soon-to-be-upcoming RPG series until I saw the news on NG about a writing contest with the theme 'End of the Worlds' and thought that this was a chance to show them off as it would probably fit the theme. Is it okay to post an extremely long story about a farm boy falling into a hole in his farm home's stable leading into an entirely new world in another universe and getting help returning home(and mainly with two more people) while an air pirate invasion is sweeping the country he's on until they fight the air pirate crew and the fighting begins to turn into a battle to save the world as they have to stop the crew from gaining a relic that would help it take over the world in many small pieces of the story?
